Sizing the motor into the SINAMICS S200 axis
The 1FL2105-4AF11-1MB0 is a SIMOTICS S-1FL2 low-inertia servomotor built to pair directly with the SINAMICS S200 drive line, so the drive firmware auto-recognises the motor on first connect and no separate parameter download is needed at commissioning. The continuous rating is Pn 2 kW at Nn 3000 rpm with Mn 6.6 Nm, while the standstill torque M0 8 Nm gives roughly 21 % headroom above rated for short acceleration phases — enough margin for a packaging index, a small gantry, or a pick-and-place Z-axis where peak torque arrives during accel/decel, not during the dwell.
Mechanical build and what the suffix codes mean for the cabinet
The 52 mm shaft height with keyed shaft and N tolerance is the standard industrial-mount configuration — the key is already on the shaft, so the coupling can be slid on without a separate alignment fixture, but N tolerance means the runout is not precision-ground for ultra-low backlash belt drives. An integrated holding brake is fitted, which removes the need for an external holding brake on vertical axes up to the motor's own rated torque — the drive still requires the brake release timing parameter set during commissioning to prevent jerk on enable. The 21-bit angular connector feedback carries absolute single-turn position over the drive link, so the axis knows its rotor angle on power-up without a homing move — relevant for any machine that loses reference on E-stop and cannot afford the seconds a homing cycle costs at restart. IP65 with oil seal means the housing is dust-tight and resists low-pressure water jets, and the shaft seal keeps cutting fluid out of the bearing — the motor is at home on a machine-tool slide or a conveyor line near a washdown zone, but it is not rated for full submersion or high-pressure/steam cleaning.
Compliance paperwork and group codes
Siemens groups this motor under Group Code R220 and Product Group X0DK; the product class flag marks it as built-to-order, which is the same line item used by procurement systems to enforce that returns and re-stocking are not the default path on receipt.
Carton, kitting, and sourcing posture
One piece ships per carton with outer dimensions 432 × 222 × 240 mm — the carton is sized for a single motor, not a multi-pack, so a kitting lead pulling a full machine build needs to plan floor space for individual boxes rather than a single pallet drop. Quotes for production volumes are handled against the BOM through independent distribution with availability confirmed at RFQ; lead time varies with build slot, and no standing inventory or same-day ship claim is made for this code.
